SPECIFICATION formingpart of Letters Patent No. 666,419, dated January22, 1901.

Application filed July 16, 1900. Serial No. 28,773. (No model.)

To to whom it may concern:

Be it known that I, PHILIP M. I-IAAS, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented or discovered certain new and useful Improvements inStraightening-Machines, of which improvement the following is aspecification.

The invention described herein relates to certain improvements inmachines for straightening bars, pipes, 850., and has for its object aconstruction and arrangement of parts whereby the rod or pipe isprogressively fed through the machine and at the same time given arotary movement, the longitudinal movement causing it to movetransversely of rolling abutments, whereby opposite bends or fiexuresare given to the rod in order to re move any bends or kinks therein.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a view, partly in elevation and partly in section, of myimproved machine. Fig. 2 is a sectional plan view, the plane of sectionbeing indicated by the line II II, Fig. 1. Fig. 3 is an end elevation ofthe machine. Fig. 4 is a transverse section of the main bending-rolls.Fig. 5 is a longitudinal section of the same. Fig. 6 is a side elevationof the main bending-rolls; and Fig. 7 is a view similar to Fig. 5,illustrating a modification of the construction of the bending-roll.

In the practice of my invention shafts 1 and 1 are mounted in suitablebearings 2 at the ends of the machine. At one end these shafts areprovided with pinions 4, which intermesh with the driving-wheel 5, whichin turn is rotated by pinion 6 on the powershaft. At the entrance end ofthe machine grooved rolls 7 are secured upon the shafts, and above theserolls is arranged a sliding bar 8, mounted in a suitable guide-frame 9,which is formed in two sections. The lower section is provided with acurved head 10, on which is adjustably secured a curved foot 11, formedon the guide-frame 9, as shown in Figs. 1 and 2. The guide-frame is heldupon the head 10 by means of bolts passing through curved slots in thefoot 11 and screwing into the head 10. This construction permits of theaxial rotation or adjustment of the guideframes for the purpose to behereinafter stated. The sliding bar 8 is moved up and down in theguide-frame by means of a screw 12, operated by the hand-wheel 13, andhas a roll 14 mounted in its lower end. The axial adjustment of the head9 permits of the axis of the roll 14 being shifted to an angle with theaxes of the rolls 7, so that the roll 14 will act as a feed for a bar,gripped between the rolls 7 and 14:. The angularity of the axis of theroll 14 to the axes of the rolls 7 will regulate the rate oflongitudinal movement of the bar through the machine. In order toincrease the capacity of the machine as regards the sizes of rods orpipes to be straightened therein, the rolls 7 are grooved, as shown, soas to permit of the gripping of small sizes of rods between the rolls 7and 14, the latter entering said groove when the small sizes of rods orpipes are being straightened. The grooves of the rolls 7 are madesufficiently wide with reference to the width of the face of the roll 14to permit of the desired angular arrangement of the latter withreference to the axes of the rolls 7 for purposes of feed.

The shafts 1 andl are provided adjacent to the rear end of the machinewith plain supporting-rolls 15. The main polishing and straighteningrolls are arranged at a point preferably midway between the rolls 7 and15. A bearing-block 16 is secured to the bed 17 of the machine by meansof bolts 18, as clearly shown in Figs. 1, 4:, and 6. The upper surfaceof this bearing-block is made concave and forms a seat for the tippingblock l9,which is held in position on the bearing-block 16 by means ofbolts 20, passing through slots in the bearing-block and bed of themachine and screwing into the carrier or tipping block 19. A curved seat21 is formed on the under side of the bed-plate 17, having a radius ofcurvature equal to the radius of curvature of the seat in the block 16.This seat forms a bearing for the heads of the bolts 20, as shown inFigs. 4 and 6. Rolls 22 are mounted upon sleeves 23, passing through thecarrier-blocks. These rolls and sleeves are connected to thedriving-shafts in such manner as to permit of the sleeves and rollsbeing shifted, so that their axes will be at an angle to the axes of therod or pipe passing through the machine. A convenient means foraccomplishing this purpose consists in enlarging the openings at theends of the sleeves, as shown in Figs. 5 and 7, so that the latter willnormally bear on the shaft only in a plane midway of the length of thesleeve. The rolls and sleeves are connected to the shaft by means of akey 24, which has a curved seat in a groove in the shafts l and 1, asshown in Fig. 5. In lieu of the form of key shown in Fig. 5, a slot 25may be formed through the shafts, the ends of the slot being enlargedlengthwise of the shaft and a key 2 .1: passed through this slot andengaging the sleeves and rolls. This construction permits of theadjustment of the axes of the rolls to any desired angle to the rodpassing through the machine. It will be seen that these rolls 22 can beadjusted at different angles, so that they will have a rubbing andpolishing action upon the surface of the bar passing through themachine.

Heads 26 are adjustably mounted upon the bed 17 on each side of therolls 22, and on the upper ends of these heads are formed curvedenlargements 10, which form seats for the feet 11 of the guide-fram es9. These guideframes 9 are made adjustable on the seats or heads 10 byforming slots in the feet, through which pass securingbolts threadedinto the seats 10 Slides 8 are movably mounted in the guide-frames 9",their adjustment being eflected by screws 12, operated by handles 13. Onthe lower ends of these slides 8 are mounted straightening-rolls 27,arranged to bear upon the rod passing through the machine. By axiallyadjusting the frames 9 these rolls 27 may be so shifted that their axeswill be at any desired angle to the axis of the rod being straightened.

In order to guide the front end of the rod or pipe up onto the rolls 22and 15 and under the rolls 27, blocks 28, having curved and inclinedseats in their upper faces, are arranged in front of the rolls 22 and15, as shown in Fig. 2, and the lower ends of the forks of the slides S,forming the bearings for rolls 27, are shaped, as shown at 28 and 29 inFig. 1, to guide the end of the rod or pipe under the rolls 27. Theouter edges of these blocks are sulficiently low to permit of the frontend of the rod passing up onto the blocks and, as the rod progresses,being forced up sufficiently high to pass onto the rolls 22 and 15.

As will be readily understood by those skilled in the art, the rod orpipe may be passed back and forth several times through the machine, ifnecessary, to produce the desired straightening and polishing thereof byreversing the direction of rotation of the rolls 7, 22, and 15. In orderthat the rod when passed in a reversed direction may be raised up ontothe rolls 22 and 7, auxiliary guides 29 are arranged in suitablerelation to the rolls 22 and 7, as shown in Fig. 1.

As will be readily understood by those skilled in the art, the rolls 7and 14 will effect the onward movement and rotation of the bar or pipe,asthe latter will be firmly gripped between said rolls, and this gripwill be sufficient to effect the onward movement of the rod, even if theseveral rolls 27 and 22 are adjusted so that their axes will be atdifferent angles to the axes of the pipe or rod, 'so that these rollswill have a polishing action, as well as flexing action, on the rod.
